The Promixis PIO-1 is a network multifunction input output device capable of sending and receiving
IR codes, network to serial conversion, digital input output and relay control. It supports DHCP and
static IP configuration.
If you are having trouble with your PIO-1 please contact [email protected] or 877.877.0643 x 1
for help.
The PIO-1 is network upgradeable using industry standard TFTP protocol. So once the PIO-1 is
installed there is no need to remove it from it's installed location to upgrade.
1. Functionality
The PIO is packed with features:
2 Serial outputs
4 IR Outputs
1 IR Input (NEC, Sony SIRC and Philips RC5, RC6 protocols supported)
3 Relays
2 bi-directional digital ports
Web configuration interface
1.1. Ethernet to Serial Bridge
The device outputs the raw data from the serial port onto the network without any conversion. With the
addition of this free software you can use the PIO-1 as a virtual comport on your computer with any
software that supports serial communications.
The serial ports can be access through the network by connecting to ports 6001 (serial 1) and 6002
(serial 2) on the device. The serial port baud rates can be configured through the web interface. Some
serial devices require power on pins 4 and 7 to operate properly (for example the UPB interface
modules). The PIO-1 provides internal jumpers (p6 and p7) to provide that.
Note that due to the inherent network behavior timing of data arrival is slightly different when using
any Ethernet to Serial bridge and some time sensitive serial protocols might not work.
1.2. IR (infra red)
The PIO-1 supports the industry standard RAW-CCF format and can output a wide range of modulation
frequencies. The PIO-1 also has a IR input that allows you to detect remote controls using the Philips
RC5, Sony SIRC or NEC IR protocol. Any universal remote will be able to send signals that the PIO-1
can recognize.
1.3. Relays
The PIO-1 has three internal relays suitable for signal level switching. The relays can be controlled
from the telnet and web interface.
1.4. Digital Input Output
The PIO-1 has 8 digital input output lines. Two of those lines are brought out to the back of the PIO-1
on the green connector block. The external lines are protected with an ESD protection circuit. Refer to
the electrical characteristics sections for the maximum draw allowed on these lines. You'll also find a
3.3V dc output on the green connector block. Please do not use more than 50mA from this.
1.5. Web Configuration
Configuration of the PIO-1 can be done through a web browser. Simply type the IP address of the PIO1 into your browser. For example
2. The API
The PIO-1 also has a telnet interface that allows you to control the various features of the device. The
telnet interface can be reached on port 6000. The API is plain text and \r\n terminated. This allows you
to control the PIO-1 manually as well as using an automation application like Girder.
If an error occurs the unit will answer “error 0,0”
2.1. Version
This commands allows you to retrieve the firmware version and the device layout.
getversion Promixis PIO-1 Firmware 1.7.0,IR:4,RELAY:3,IO:2,SERIAL:2
2.2. Relays
These commands give you full control over the relays. <relay> is the index of the relay either 1, 2 or 3.
<state> is 0 for open and 1 for closed.
Change relay status
setrelay <relay>,<state>
Relay Status request.
getrelay <relay>
getrelay <relay>,<state>
2.3. Digital IO
Digital IO ports (<pin>=1-8) have three registers. A direction register, an output register and an input
register. Pin's 1 and 2 are the external pins. <direction> can be 0 for input and 1 for output. <state> can
be 0 for off and 1 for on. These are manipulated through the following requests.
Set Direction:
setddr <pin>,<direction>
Get Direction:
getddr <pin>
getddr <pin>,<direction>
Set Port (output value / pull ups)
setport <pin>, <state>
Get Port (output value / pull ups)
getport <pin>
getport <pin>,<state>
Get Pin (input) value
getpin <pin>
getpin <pin>,<state>
Whenever the value of an input changes the unit automatically sends the following notification
pinchange <pin>,<state>
2.4. IR Sending
IR signals can be sent using industry standard CCF codes. Since sending can take a bit of time with
longer repeats or CCF codes the unit will acknowledge the request with “ok” and later send “irdone”
when the sending is actually finished. Do not try to send a new IR signal before the last has finished.
sendccf <BITMASK>,<REPEAT>,<CCF>
<BITMASK> is bitmask of the 4 outputs, and accepts values between 1 and 15. If you wish to
send an IR signal out the first port use bitmask 1. The second port has bitmask 2. The third port
has bitmask 4 and the fourth port has bitmask 8. You can combine these in any way you like.
<REPEAT> is the number of times to repeat the signal.
<CCF> is the RAW-CCF code to send.
Example: sendccf 15,20,0000 006E 0022 0022 0156 00A9 0015 0012 0015 003F 0015 003F 0015

2.6. Get MAC address
Returns the MAC address for the unit.
getmac 00:1B:C5:03:B0:01
2.7. Remote Detection
The PIO-1 recognizes 3 IR protocols and notifies the listener on the telnet connection.
Philips RC5
rc5 <toggle bit>,<address>,<command>\r\n
Philips RC6
rc6 <toggle bit>, <address>,<command>\r\n
Sony SIRC (12,15 and 20 bits)
sirc <address>,<command>\r\n
NEC protocol
nec <address>,<command>\r\n
3. Firmware updating / Factory Reset
You can update or factory reset the PIO-1 using the PIO-1 tool available from the Promixis website.
4. Unit Detection
The PIO-1 will periodically transmit a UDP
broadcast packet containing it's current IP address.
This allows you to find PIO-1 on your network's
subnet and determine which IP address the PIO-1
has taken on the network.
The destination port for this broadcast is: 5998 IP
The packet contains the string: PIO1,1.7.7,,00:1B:C5:03:B0:00 which is
the name, the firmware version, the ip address and
it's hardware address.
The Promixis PIO-1 Tool allows you to find the PIO-1's easily on the network and upgrade them as
needed. You can find this tool at
5. UDP Communications

6. Troubleshooting
If for any reason a firmware upgrade fails or you need to turn DHCP back on to get the PIO-1 back on
the network use the following procedure.
1. Find a IR remote with new batteries
2. Unplug the PIO-1
3. Point the IR remote at the rectangular hole marked IR-in and press a button on the remote.
4. While holding the button on the remote power up the PIO-1.
5. The PIO-1 will now set the DHCP server option to 1 and also check if a TFTP server is available
with new firmware.
